T 0 all-whom it may concern: .1

Be it known that I MosEs-A. M LLnn, a citizen of the United States of America,and

resident of St. Albans, in the county of Franklin and State of Vermont,, -have 1 nvented certain new anduseful Improvements in Sash Locks and Holders, of which the with means for holdingthe window el vated at different positions of adjustment;

A further object of'th'isinvention is to provide a sash lock Or'hOlder, the operating pai' 'ts of which maybe concealed and made inaccessible, in order that""they c'annot hbe tampered with by enautherizedpersenato produce a sash lock and holder of the character indicated which will prove effective and durable and which will not mar the appearance of the window or parts thereof.

With the foregoing and other ob]ects 1n view, the invention consists in. the details of constructiomand in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will I be had to the accompany ng drawings forming part of this application wherein like characters denote corresponding parts in theseveralviews,andinwh1ch- Figure 1 illustrates a view in elevatlon of a sash showing the frame and parts associated With it in section;

Figure 2 illustrates a view in elevation of the sash and frame showing the latch operating parts in elevation;

Figure 3 illustrates a sectionalvlew on a line corresponding with the line 3-3 of i 2'- h iglire 4' illustrates a view in elevation of the latch and plate; v Fi re 5 illustrates a VlGW in perspective of the latch detached; and

Figure 6 illustrates a perspective view of a latch retaining spring.

In these drawings 10 denotes a sash having a plate 11 constituting a face of its edge;

the said sash having a series of recesses 12 forming seats for irregularly shaped offset portions 13 of the saidface plate. The off- -21, the lower edge-of'which is shaped to set portions 13 have shouldersi".aout- 'wardly inclined wallsi'merging' wv-ithziathe outer surface of the faceplate,=:,and*thezsaid face plate also has an offset:portionzsloiwith ashoulderlti at the bottom; the said shoulder '66 being inclined from'the surfacejofithe face plate to the inner edgev or .w'allv ofthe said recess for the 'purpose vof' engaging :a latch,

:as will presently. appear, to'p'reven't the slidy I 17 is oscillatable'onl a pivot 18 carried bythe housing19 which is ing of :thesash.

The latch or dog imbedded in the sashi frame 20 'with-f relation a) which the sash slides. The dog has a1inose the contour of the" shoulder 16, in i'o'rder to form an interlocking engagement therewith which ill revent cammin oi thenose of;

the dog with 'relationato 'the socket. of the n faceplate, even thou h pressure is applied 1" A still. further object of thls inventlon 1s to the sash from below. The 'upperedgefof thenose of the dog isapproximatelystraight and it is adapted to be engaged byany one of the shoulders '14 when the sash is elevated, and the dog is then effective to hold the sash in different positions of adjustment. A lug 22 on the upper end: of the dog abuts an inner wall of the housing and serves to retain the dog in position against the action. of a spring 23, which spring is operative to force the free end of the dog normally outward. The spring has an angularly dis posed foot 241: which'fits' in a recess 25 of the housing whereby it" is anchored in operative relation to the dog.

' The dog 17 is pressed inwardly to force.

,is integral with the dog. 'Ifdesired, the push rod may be remo-vably' applied to the frame so that whenthe sash is held-locked,

' there'jwill be nothing exposed which might be manipulated by unauthorized persons for the purpose -,of operating the dog The housing is, of such construction as to form a seat for the spring, as fully shown in Fig. 1; and it is believed that {one skilled i in the art will understand that the action of the dog will be such as to hold the sash locked when the parts are in the positions shown in'Fig. 1, whereas when the dog is pushed inwardly, the sash maybe elevated" and it will also be understood that the dog will serve to engage one of the shoulders 14 of the face plate and retain the sash at different positions of adjustment.

I claim:

1. In a sash lock and holder, a sashhaving a face plate with recesses formed therein withshoulders at the upper ends of the recesses and a recess having an inclined shoulder at its lower end, a dog pivotally mounted in a window casing and having a nose projecting therefrom adapted to enter the-"recesses of the face plate, the said dog having a lower edge adapted to engage the inclined shoulder of one of the recesses and a straight upper edge adapted to engage the shoulders of the other recesses, means for urging the nose of the dog into operative relation with the said shoulders, a laterallyextending arm carried by the dog,

and manually operated means engaging the arm for pushing the dog against the action of the said urging means.

2. In a sash lock and holder, a sash having a face plate with recesses formed there in with shoulders at the upperends of the recesses-and a recess having an inclined shoulder atits lower end, a dog pivotally mounted in a window casing and having a nose. projecting therefrom adapted to enter the recesses of the face plate, the said dog having a lower edge adapted to engage the inclined shoulder of one of the recessesand a straight upper edge adapted to engage the shoulders of the other recesses, means for from the edge of thefraine, a spring anchored in the casing and bearing against thedog to hold it normally outward, an inclined surface on the lower edge of the nose of the dog and a straight surface on the upper edge of the nose, a sash having recesses, a face plate attached to the edge of the sash and having irregular contour fitting the recesses of the sash, an inclined shoulder forming the lower wall of one of the irregularities of the face plate, shoulders at the upper ends of the other irregularities ofthe face plate and inclined surfaces therebelow merging with the outer surface of the plate with relation to which the nose of the dog coacts, and means for pushing the. nose of the dog'out of engagement with the face plate.
